No. 86, Ellsworth and Highland (steps)
There is much news to report.
First, we’ve found two more protractors. No. 86 (seen above) recently appeared on the staircase from Ellsworth to Highland, halfway down from its brother, No. 87 (also seen above, a rare double). No. 180 (after the jump) is at Ellsworth and Negley.
Second, Mark R took the initiative of creating a Google Map of the protractors and logging his five entries. In the coming weeks, I hope to add all the previously found protractors — sixty altogether — including pictures, locations, numbers and colors.
UPDATE (June 20, 2013): There is a new digital map, in progress, here.
Third, I’ve updated the Master List.

Much thanks! I’ll add it to the map.
Ever think of making the same map for all the Thor tags & Yoshi eggs around the city?
Sybertron,
I’ve considered it and even collected photographs, but it would take a more concerted effort than I have time for at the moment. Perhaps in the future sometime.
